Galvanic corrosion

Galvanic corrosion (also called bimetallic corrosion or dissimilar metal corrosion) is an electrochemical process in which one metal corrodes when it is in electrical contact with another, different metal, and both are in the presence of an electrolyte. A similar galvanic reaction is exploited in single-use battery cells to generate a useful electrical…
